What is an umbilical hernia? An umbilical hernia is a bulge through the abdominal muscles in the area of the navel (belly button). The hernia may contain tissue from the abdomen, part of an organ (such as the intestine), or fluid.
Iliac crest contusion occurs due to bleeding of abdominal muscles and swelling. This can cause excruciating pain when the person tries to move his hip region. Bleeding can occur on the periosteum region of the bone resulting in inflammation and the muscles of the iliac crest would develop spasms.
Injury to the gluteus muscles may cause this movement to respond to the muscle tightening and resulting nerve compression with pain. Referred pain patterns from a tight G. medius will usually form an arc along the top of the hip bone (iliac crest area), down into the buttock and across the sacrum.
